# Progress #
* TCWG-923, Use regcache instead of frame in software_single_step. [1/20]
Patches are pushed in. Done.
* TCWG-333, Fix gdb.base/func-ptrs.exp fails in thumb mode. [3/10]
Another three preparatory patches are approved. Ongoing.
* TCWG-416 Improve GDB performance in remote debugging. [3/10]
Prologue analysis performance on arm-linux is improved a lot (from
39s to 12s in one case), but no change on aarch64-linux. Looks GDB
doesn't recognise "str x19, [sp, #-48]!" as part of the prologue.
* TCWG-965 Unit test in GDB. [2/10]
Investigate how to do unit test to prologue analysis in GDB, to
address the bug above. We can embed some test code in GDB, and invoke
them by a special command. It is a little big ugly, but better than
nothing. Need some refactor to aarch64 backend for unit test.
* Patches review, [1/10]
** Reviewed two new GDB ports, RISC-V and OpenRISC.
** Chat with Antoine on ptrace atomicity, and insist that he should
refactor 'struct tracepoint' before add arm-linux tracepoint
support.
